APPARATUS FOR oooLme CAR-AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 360,978, dated April12, 1857.

Application filed September 2, 1886 To all whom it may concern.-

Be it known that I, JEROME EUGENE TOURNE, of New Orleans, in the parishof Ornew and useful Improvement in Apparatus for Cooling Gar-Axle Boxes,of which the following is a specification.

My invention consists in an improved apparatus, which will behereinafter fully described and claimed, for cooling and preventing firein car-axle boxes of railroad-cars by the utilization of theexhaust-steam from the a powerful flow of steam direct from the boilerwhenrequired.

Referring to the accompanying drawings, Figure 1 is a plan view of adevice embodying my invention. Fig. 2 is a detail of a modification.

. Referring to the several partsby letter, A

B indicates the main pipe, which is supported in a suitable position onthe locomotive, its two branches, BB, extending on each side of theboiler, being flexibly connected at their forward open ends by means ofrubber or other flexible tubes, 0 O, with the exhaustoutlets of thesteam-cylinders of the locomotive. The main pipe B is also connecteddirectly to the boiler by a connecting-pipe, D, having a stop-cock, E,which may be opened to admit the steam direct from the boiler into themain pipe. I I

-13 indicates the sections of the main pipe A, which are secured beneaththe several cars of a train, one beneath each car, and G indicateslateral branch pipes, which extend from the pipes F near each end of thesame, and lead to or within the car-axle boxes, as the construction ofthe latter may render desirable, the ends of the lateral pipes Gcommunicating with the axle-boxes through flexible couplings H. Theforward part of the main pipe,which is secured on the locomotive and itsseveral sections beneath the different cars, are connected one to theother by flexible couplings so that the cars may be readily separated,when required, without any further disturbance to Serial No. 212,553.(No model.)

the apparatus than the uncoupling of the flexible couplings of the pipesbetween the cars.

It will be seen that the waste or exhaust steam from the twosteam-cylinders of the 10 comotive will continually pass through theseveral sections of the main pipe when the latter have been coupledtogether, and will pass through the lateral pipes G into each of thecar-axle boxes of the train, the steam when entering these boxesbeingnearly at the point of condensation; and it will be seen that the steamwill thus efi'ectually maintain the temperature in the boxes at a pointbelow that at which there is danger of ignition, thus entirelypreventing hot boxes or conflagrations, and

serving also as a lubricant.

When required, the stopcock E may be opened, thus' sending a powerfulflow of steam direct from the boiler through the pipes and into theseveral axle-boxes to lower the heat of any box that might becomeoverheated when running at a high rate of speed.

The main pipe may also have a dischargepipe, K, in the form of asprinkler, near the stop-cock E, which may utilize the steam to destroygrass or weeds growing on the track.

From the foregoing description,taken in connection with the accompanyingdrawings, the construction, operation, and advantages of my improvedapparatus will readily be understood. It will be seen that it is verysimple in construction, while at the same time it is very efficient inits operation. The waste steam is utilized to cool the axle-boxes andprevent ignition, while a powerful flow of steam may be thrown throughthe pipes direct from the boiler when required.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, 1s-

1. The combination, with a locomotive, of the main pipe having theforward branches communicating with the exhaust-outlets of thesteam-cylinders thereof and the sections connected together by theflexible couplings, and having the lateral pipes communicating with eachof the car-axle boxes, substantially as and for the purpose herein set.forth.

2. The combination, with a locomotive, of the main pipe having theforward branches communicating with the exhaust-outlets of the pipehaving the stopcock, and the sections connected together by the flexiblecouplings, and having the lateral pipes communicating with each of thecar-axle boxes, substantially as and for the purpose herein set forth.

3. The combination, With a locomotive, of the main pipe having theforward branches communicating with the exhaust-outlets of the steamcylinders thereof, communicating di- Y rectly with the boiler throughthe connectingpipe having the stop-cock, the discharge-pipe in the formof a sprinkler, and the sections connected together by the flexiblecouplings, and having the lateral pipes communicating with each of thecar-axle boxes, substantially as and for the purpose herein set forth.

' 4. The combination, with a locomotive, of 20 the main pipe having theforward branches communicating through flexible pipes with theexhaust-outlets of the steam-cylindencom; municating directly with theboiler through the connecting-pipe having the stop-cock, and 25 thesections connected together by the flexible couplings, and having thelateral pipes communicating through the flexible couplings with each ofthe car-axle boxes, substantially as and for the purpose herein setforth.
